What is Flash Recovery Area and Datafile Location.

The Oracle base is your starting point for the default
locations of all datafiles and the flash recovery
area. Oracle recommends that you place the Oracle home,
the Oracle datafiles, and the flash

recovery area on separate mount points, as shown in the following example:

$ORACLE_BASE/flash_recovery_area
$ORACLE_BASE/oradata
$ORACLE_BASE/product/11.1.0/db_1


in an Oracle RAC installation, you share the flash recovery area and the datafiles
among the different nodes of the RAC.
